justedv, in each case, correspond with the work or resistance required. It will thus be understood that the; size and angles of the teeth and the tension and. adjustment of the spring must :be adapted to the weight and size of the window and the conditions under which a'particular window is toA be employed.

What I clairn is:

1. In `va device ofthe character described, o, the combination of an arm having an an` nular toothed flange at one endand, a pivot pin projecting fromy said arm and located concentrically of said vtoothed `flange, *said parts being formed integrally; a second arm having an annular toothed `flange and an opening` concentric therewith for receiving vsaid pin, said toothed anges intermeshing with each other; a coiled springsurrounding said pin; a tubular cap ymounted on said pin and constituting a housing for said spring; and means secured upon the outer end of said pin and overlapping the end of said cap for holding said parts in assembled relation, Whereby said housing and pivot pin turn with said first arm.
